Title: Apparatus and method for compensating mass flow rate of a material when the density of the material causes an unacceptable error in flow rate
Inventor: PATTEN ANDREW T
IPC: G01F15/02
Filed: 2001-10-26
Abstract: An apparatus (150) and method (300) for determining a density compensated flow rate of a material flowing through a vibrating conduit. Signals are received from sensors (105, 105') affixed to the vibrating conduit (103A, 103B). An uncompensated flow rate of said material is then calculated from the signals. A density compensation factor is then determined from the uncom-pensated flow rate and non-linear information relating density to errors in flow rate. The density compensated flow rate is then determined by applying the density compensation factor to the uncompensated flow rate.
Patent CA-2425044-A1 (CA)
Inventor: WATSON JULIAN MARK
IPC: C05F17/02
Filed: 2001-08-23
Abstract: A composing system which includes a stationary and usually unheated generally horizontal composting chamber with an inlet and outlet at oposite ends of the chamber. Through the middle of the chamber may be a shaft or shafts to which are attached a series of discrete arms, appendages or flutes that extend into the outer volume of the chamber. The arms mix and agitate a composting material placed in the inlet and transport the compost material to the outlet at the other end of the chamber while the material composts and biodegrades in the chamber. The arms allow air to penetrate into the composting material and to release water through the emission of steam. A number of probes through the exterior of the chamber which extend into the headspace of the chamber, or into the copositing mix measure temperature and carbon dioxide levels with the chamber.

Title: An anti-angiogenic state in mice and humans with retinal photoreceptor cell degeneration
Inventor: PASQUALINI RENATA
IPC: A61K31/24
Filed: 2002-07-17
Abstract: Neonatal mice with classic inherited retinal degeneration (Pdebrdl/Pdebrdl) are disclosed which fail to mount reactive retinal neovascularization in a mouse model of oxygen-induced proliferative retinopathy. Also disclosed is a comparable human paradigm: spontaneous regression of retinal neovascularization associated with long- standing diabetes mellitus which occurs when retinitis pigmentosa becomes clinically evident. Both mouse and human data indicate that reactive retinal neovascularization either fails to develop or regresses when the number of photoreceptor cells is markedly reduced. The results show that a functional mechanism underlying this anti-angiogenic state is failure of the predicted up-regulation of vascular endothelial growth factor (VEGF), although other growth factors may also be involved. Preventive and therapeutic methods useful against both proliferative and degenerative retinopathies are also disclosed.
